See the man pages on automount and autofs. File systems can be setup to
mount only when accessed or needed. Automount systems typically don't mount
the file system until it is actually needed and then umount it after some
length of inactivity (10 minutes on Solaris).
Hope this helps.

Subject: Relying on NFS availability
My users server does an NFS mounts of /var/mail from another system.
If
for some reason all servers happen to get restarted (power failure comes
to
mind), the mail spool server takes longer to boot up than the users one.
Consequently /var/mail never get mounted until I manually try to re-run
netfs.
Is there some way of checking whether an NFS mount is actually mounted
for some
time after a system boots up? What I'm thinking of here is some script
that
can run for maybe an additional 15 minutes after the system restarts,
checking
whether all NFS mount points are actually available. If everything is
mounted,
it kills itself, otherwise it continues to try for maybe up to 15
minutes then
exits. I figure if after 15 minutes the other system isn't up yet,
things have
gone to fritz.
Does something like this already exist? Is there some other
solution if
this isn't the proper way of doing it? Ideally I'd like to delay
sendmail's
startup as well otherwise incoming mail will get stored on the physical
(local)
/var/mail and when the NFS mount becomes available, I have to moves
those
files, do a remount, then cat those files back into the user's mailbox.
This
is annoying.
